Definitions
- the invention is related to a high pressure pipe coupling construction according to the preamble of claim 1.
- Such a coupling construction is known from EP-A-2045501 , and relies on the clamping force which is exerted by the sleeve clamping parts on the pipe wall.
- the pipe wall is introduced between the sleeve clamping parts which are at a relatively large distance from each other.
- the sleeve clamping parts are pressed towards one another whereby the pipe wall is squeezed.
- one or both sleeve clamping parts is/are plastically deformed, in such a way that a permanent connection between the pipe and the coupling is obtained.
- the threads of the reinforcement layer should be held clamped securely, as these threads play an important role in transferring forces between the pipe and the coupling.
- the prior art coupling constructions may give rise to problems. These problems occur as a result of the circumstance that the axial clamping length, that is the length of the sleeve clamping parts, inevitably is limited. First of all such limited clamping length is necessary for enabling the insertion of the pipe wall in the annular space defined between the sleeve clamping parts. In case the axial dimension of the annular space is too long, it may become impossible to fully insert the pipe wall. Furthermore, a coupling with relatively long sleeve clamping parts is difficult to manufacture and the manufacturing costs thereof would be high. Also, the effectiveness of relatively long sleeve clamping parts with respect to force transfer is limited.
- the object of the invention is to provide a coupling construction of the type before which is fit for very high operating pressures and which does not run the risk of premature failure. This object is achieved by the characterising features of claim 1.
- the coupling applied in this coupling construction has sleeve clamping parts which are of an axial dimension which is comparable to the traditional coupling. This means that the advantages of the traditional coupling, that is proper insertion of the pipe wall and acceptable manufacturing costs, are, maintained.
- an extended sleeve part has been provided which provides several additional advantages to the coupling. This extended sleeve part can be attached to or integrated in the prior art coupling. It does not overlap the other coupling parts, which means that it can be easily applied, and in an economic way.
- the extended sleeve part provides a highly improved connection between the pipe and the coupling.
- the traditional coupling construction relied on the clamping action of the sleeve clamping parts on the pipe wall.
- the threads of the reinforcement layer are thereby held captive between said sleeve clamping parts as well. This effect is maintained in the inventive coupling construction as well.
- the extended sleeve part provides an additional effect which did not, or hardly, play a role in the traditional coupling construction and which greatly enhances the load which can be transferred.
- the corresponding liner part of the pipe is also held pressed in outward direction.
- the thread parts which are wound around this liner part are unable to slip, because the thread parts located at the pipe wall end are held.
- the thread parts wound around the liner part at the position of the extended sleeve part may develop a high pulling force with respect to the liner, similar to the above cable wound around a bollard.
- the shape of the coupling, in particular of the extended sleeve part is influenced in such a way that the pulling force can be maximized. Therefore, the inner surface of the outer sleeve clamping part and at least the adjoining inner surface part of the extended sleeve part, when seen in an axial cross section, are in line with each other. Both the sleeve clamping parts and the extended sleeve parts have cylindrical surfaces.
- the inner cylindrical surface of the outer sleeve clamping part is of the same diameter as the inner cylindrical surface of the extended sleeve part, at least at the transition between these parts.
- an inner surface of the extended sleeve part which is positioned at a location beyond the inner surface part of the extended sleeve part which adjoins the inner surface of the outer sleeve clamping part, when seen in an axial cross section, has a slightly widening shape or trumpet shape in the direction towards the free end of said extended sleeve part.
- the length over which the pipe wall is supported with respect to the extended sleeve part may vary.
- a further improvement of the connection between the coupling and the pipe may be obtained by teeth on the inner surface of the outer sleeve.
- the inner surface of the outer sleeve clamping part comprises relatively coarse teeth.
- the inner surface of the extended sleeve part comprises relatively fine teeth.
- the coupling construction may be carried out in several ways, such as with a coupling which comprises a connection piece for connection to another coupling, or to a flange and the like.
- the threads may be applied by winding these individually.
- the reinforcement comprises helically wound tapes which each comprise threads which are juxtaposed, when seen in circumferential direction of the pipe.
- the threads preferably consist of a material with a high strength and high stiffness, such as steel wire or aramid.
- the tensile modulus of elasticity may be more than 50 GPa.
- the coupling may consist of steel.
- the coupling construction shown in figure 1 consists of the coupling 1 and the high pressure pipe 11.
- the coupling has a coupling piece 2, which can for instance be connected to a similar coupling in mirror fashion so as to connect two pipes together.
- the coupling piece may be provided with a flange 3 for connection to e.g. a vessel.
- the coupling 1 has an outer sleeve 4 and an inner sleeve 5.
- the coupling 1 may be of circular cross section, in which case said sleeves 4, 5 are coaxial.
- the outer sleeve 4 consists of the outer sleeve clamping part 6 and the extended sleeve part 7 which forms a unity with the outer sleeve clamping part 6 in the embodiment shown.
- the inner sleeve 5 consists of the inner sleeve clamping part 8 which is opposite the outer sleeve clamping part 6 and overlaps same.
- the outer sleeve clamping part 6 has relatively coarse internal teeth
- the extended sleeve part 7 has relatively fine internal teeth 10.
- the area of the extended sleeve part 7 which adjoins the outer sleeve clamping part 6 is in alignment with said outer sleeve clamping part, when seen in the longitudinal section of figure 1 . In the case of a circular coupling piece 1, these parts merge smoothly into each other. Additionally, the area of the extended sleeve part 7 near the free end thereof may widen somewhat in radial direction, or is trumpet shaped.
- the high-pressure pipe 11 comprises an inner lining 12, a reinforcement layer 13 and a coating 14.
- the reinforcement layer 13, which is shown in top view in figure 2 consists of helically wound threads 15,16 which are positioned at opposite angles.
- the piece of the wall 17 of the pipe 11 near the free end thereof is clamped between the outer sleeve clamping part 6 and the inner sleeve clamping part 8.
- Several existing tools can be used to this end; as these tools are well known, a further description thereof will be omitted.
- the coating 14 is also pressed against the extended sleeve part 7. As a result of the presence of the fine teeth 10 on the inner surface of the extended sleeve part 7, the liner 14 and thus the pipe 11 can settle under the influence of the internal pressure within the pipe 11 and can be held with respect to this extended sleeve part 7.

Description
- The invention is related to a high pressure pipe coupling construction according to the preamble of claim 1.
- Such a coupling construction is known from
EP-A-2045501 , and relies on the clamping force which is exerted by the sleeve clamping parts on the pipe wall. Initially, the pipe wall is introduced between the sleeve clamping parts which are at a relatively large distance from each other. Subsequently, by applying appropriate tooling which is known per se, the sleeve clamping parts are pressed towards one another whereby the pipe wall is squeezed. In this process, one or both sleeve clamping parts is/are plastically deformed, in such a way that a permanent connection between the pipe and the coupling is obtained. In particular, the threads of the reinforcement layer should be held clamped securely, as these threads play an important role in transferring forces between the pipe and the coupling. - However, in this respect the prior art coupling constructions may give rise to problems. These problems occur as a result of the circumstance that the axial clamping length, that is the length of the sleeve clamping parts, inevitably is limited. First of all such limited clamping length is necessary for enabling the insertion of the pipe wall in the annular space defined between the sleeve clamping parts. In case the axial dimension of the annular space is too long, it may become impossible to fully insert the pipe wall. Furthermore, a coupling with relatively long sleeve clamping parts is difficult to manufacture and the manufacturing costs thereof would be high. Also, the effectiveness of relatively long sleeve clamping parts with respect to force transfer is limited. It appears that force transfer mainly takes place over a rather short part of the sleeve clamping parts, which parts are thus highly stressed. The remaining, largest part of the sleeve clamping parts practically does not share in the transfer of forces. This leads to the risk that the relatively short part fails, which in the end would lead to the failure of the complete coupling construction.
- Thus, in practice it appears that under certain circumstances the clamping length is too small to withstand the forces which occur in practice. Especially when operation takes place under high surface pressures of 20.000 bar.cm2 or more, the threads in the clamped area may start to slip as a result of which the coupling construction will fail.
- The object of the invention is to provide a coupling construction of the type before which is fit for very high operating pressures and which does not run the risk of premature failure. This object is achieved by the characterising features of claim 1.
- The coupling applied in this coupling construction has sleeve clamping parts which are of an axial dimension which is comparable to the traditional coupling. This means that the advantages of the traditional coupling, that is proper insertion of the pipe wall and acceptable manufacturing costs, are, maintained. In addition however, an extended sleeve part has been provided which provides several additional advantages to the coupling. This extended sleeve part can be attached to or integrated in the prior art coupling. It does not overlap the other coupling parts, which means that it can be easily applied, and in an economic way.
- More importantly however, the extended sleeve part provides a highly improved connection between the pipe and the coupling. As mentioned before, the traditional coupling construction relied on the clamping action of the sleeve clamping parts on the pipe wall. The threads of the reinforcement layer are thereby held captive between said sleeve clamping parts as well. This effect is maintained in the inventive coupling construction as well. However, the extended sleeve part provides an additional effect which did not, or hardly, play a role in the traditional coupling construction and which greatly enhances the load which can be transferred.
- This effect is comparable to the so-called capstan effect which occurs when winding an anchor cable around a bollard. The cable is wound around the bollard with a few windings. As a result thereof, when the free end of the cable is pulled with a relatively low holding force, e.g. by hand, said windings make that a large pulling force can be exerted in the cable. In the pipe according to the invention, the thread parts located at the pipe wall end which is clamped between the sleeve clamping parts are held with a certain holding force. Under the influence of the internal overpressure in the pipe, the pipe part outside the sleeve clamping parts which overlaps the extended sleeve part, is held pressed against said extended sleeve part. Consequently, the corresponding liner part of the pipe is also held pressed in outward direction. The thread parts which are wound around this liner part are unable to slip, because the thread parts located at the pipe wall end are held. Thus, the thread parts wound around the liner part at the position of the extended sleeve part may develop a high pulling force with respect to the liner, similar to the above cable wound around a bollard.
- In the prior art coupling construction, only the effect of holding the threads at the clamped location will occur. However, just outside said location the pipe wall will try to expand under the influence of the internal overpressure. This expansion is counteracted by the threads, however the winding effect of the threads around said expanded section is appreciable less or even absent, thus, the beneficial capstan effect will be virtually absent, such that the pulling force in the threads cannot increase above the mere holding force at the clamped location.
- The shape of the coupling, in particular of the extended sleeve part, is influenced in such a way that the pulling force can be maximized. Therefore, the inner surface of the outer sleeve clamping part and at least the adjoining inner surface part of the extended sleeve part, when seen in an axial cross section, are in line with each other. Both the sleeve clamping parts and the extended sleeve parts have cylindrical surfaces. The inner cylindrical surface of the outer sleeve clamping part is of the same diameter as the inner cylindrical surface of the extended sleeve part, at least at the transition between these parts.
- Furthermore, with the aim of providing a smooth transition between the pipe part which is supported by the extended sleeve part, and the free part of the pipe, an inner surface of the extended sleeve part which is positioned at a location beyond the inner surface part of the extended sleeve part which adjoins the inner surface of the outer sleeve clamping part, when seen in an axial cross section, has a slightly widening shape or trumpet shape in the direction towards the free end of said extended sleeve part.
- The length over which the pipe wall is supported with respect to the extended sleeve part may vary. With the aim of obtaining the desired capstan effect, preference is given to an embodiment according to which the sum of the axial length of the outer sleeve clamping part and the axial length of the extended sleeve part is at least 1,5 times the axial length of the inner sleeve clamping part. More preferably, the sum of the axial of the outer sleeve clamping part and the axial length of the extended sleeve part is at least 2 times the axial length of the inner sleeve clamping part.
- A further improvement of the connection between the coupling and the pipe may be obtained by teeth on the inner surface of the outer sleeve. Preferably, the inner surface of the outer sleeve clamping part comprises relatively coarse teeth. Furthermore, the inner surface of the extended sleeve part comprises relatively fine teeth.
- The coupling construction may be carried out in several ways, such as with a coupling which comprises a connection piece for connection to another coupling, or to a flange and the like.
- The threads may be applied by winding these individually. However, an embodiment is also possible wherein the reinforcement comprises helically wound tapes which each comprise threads which are juxtaposed, when seen in circumferential direction of the pipe. The threads preferably consist of a material with a high strength and high stiffness, such as steel wire or aramid. As an example, the tensile modulus of elasticity may be more than 50 GPa. The coupling may consist of steel.
- The invention will now be described further with respect to the embodiment shown in the drawing.
-
Figure 1 shows a partial longitudinal section through a coupling construction. -
Figure 2 shows the view according to II offigure 1 . - The coupling construction shown in
figure 1 consists of the coupling 1 and thehigh pressure pipe 11. The coupling has a coupling piece 2, which can for instance be connected to a similar coupling in mirror fashion so as to connect two pipes together. Alternatively, the coupling piece may be provided with a flange 3 for connection to e.g. a vessel. Furthermore, the coupling 1 has an outer sleeve 4 and aninner sleeve 5. The coupling 1 may be of circular cross section, in which case saidsleeves 4, 5 are coaxial. - The outer sleeve 4 consists of the outer sleeve clamping part 6 and the extended sleeve part 7 which forms a unity with the outer sleeve clamping part 6 in the embodiment shown. The
inner sleeve 5 consists of the inner sleeve clamping part 8 which is opposite the outer sleeve clamping part 6 and overlaps same. The outer sleeve clamping part 6 has relatively coarse internal teeth, the extended sleeve part 7 has relatively fineinternal teeth 10. The area of the extended sleeve part 7 which adjoins the outer sleeve clamping part 6 is in alignment with said outer sleeve clamping part, when seen in the longitudinal section offigure 1 . In the case of a circular coupling piece 1, these parts merge smoothly into each other. Additionally, the area of the extended sleeve part 7 near the free end thereof may widen somewhat in radial direction, or is trumpet shaped. - The high-
pressure pipe 11 comprises aninner lining 12, areinforcement layer 13 and acoating 14. Thereinforcement layer 13, which is shown in top view infigure 2 , consists of helically woundthreads wall 17 of thepipe 11 near the free end thereof is clamped between the outer sleeve clamping part 6 and the inner sleeve clamping part 8. Several existing tools can be used to this end; as these tools are well known, a further description thereof will be omitted. By clamping thewall 17 between these sleeve clamping parts 6, 8, also thethreads - As result of the inner pressure in the
pipe 11, the pipe wall thereof outside the clamping parts 6, 8 is firmly pressed against the inner surface of the extended sleeve part 7. Thus, also the lining 12 of thepipe 11 is held firmly pressed in upward direction, and the part which overlaps the extended sleeve part 7. Thethreads reinforcement layer 13 are held between the sleeve clamping parts 6, 8, as mentioned before. Upon the application of a high internal pressure within thepipe 11, thethreads threads liner 12. Thereby, the so-called capstan effect is obtained which means that thethreads liner 12. - The
coating 14 is also pressed against the extended sleeve part 7. As a result of the presence of thefine teeth 10 on the inner surface of the extended sleeve part 7, theliner 14 and thus thepipe 11 can settle under the influence of the internal pressure within thepipe 11 and can be held with respect to this extended sleeve part 7. - A further settling of the
pipe 11 resulting from the high internal pressures can be attained due to the trumpet shape of the extended sleeve part 7.
